Summary: Researchers have developed a breakthrough system to deliver large therapeutic molecules into the brain, overcoming the challenges of the blood-brain barrier. The innovative blood-brain barrier-crossing conjugate (BCC) platform utilizes a biological process called γ-secretase-mediated transcytosis to safely transport drugs like oligonucleotides and proteins into the central nervous system via intravenous injection.

In mouse models and human brain tissue, the system effectively silenced harmful genes linked to diseases such as ALS and Alzheimer’s without causing significant side effects. This advancement could revolutionize treatments for neurological and psychiatric disorders, solving a critical challenge in brain research.

The Public Utilities Commission of Texas (PUCT) on Thursday adopted a rule requiring virtual currency mining facilities in the region maintained by the Energy Reliability Council of Texas (ERCOT) to register with the commission. In these registrations, the PUCT seeks each facility to share its location, ownership information and demand for electricity.

Cryptocurrency mining, in which computers crack codes in order to verify crypto transactions, has been on the rise in Texas for the past few years, specifically after China banned the practice in May 2021. The state itself was luring miners to set up shop here, offering relative regulatory freedom at first. But in the last year, Texans have been speaking out against the mines, which operate scores of their large computers at all hours of the day. The computer usage, coupled with the fans required to cool down the hard-working machines, can use up a lot of power and make the kind of noise that residents say make them sick.

Physicist Francis Perrin sat at a nuclearfuel-processing plant down in the south of France, thinking to himself: “This cannot be possible.” It was 1972. On the one hand, there was a dark piece of radioactive natural uranium ore, extracted from a mine in Africa. On the other, accepted scientific data about the constant ratio of radioactive uranium in ore.

Examination of this high-grade ore from a mine in Gabon was found to contain a lower proportion of uranium-235 (U-235) — the fissile sort. Only a tiny bit less, but enough to make the researchers sit back and scratch their heads.
